Every day this week, we’ve been providing a close-up look at one of the new features in Adobe Photoshop CS5. We wrap up the week by examining what host Deke McClelland calls the “most ambitious innovation” in Photoshop CS5: its new painting tools.

In today’s installment of Photoshop CS5 Top 5, Deke demonstrates Photoshop’s bristle brushes, which simulate traditional paint brushes—the kind your local art-supply store sells—and its new Mixer brush, which lets you give a photo a painterly look. Along the way, Deke passes along a tip for customizing Photoshop’s interface—one of those little chores that can save so much time, but that so few of us do.

We hope you’ve enjoyed this tour of Deke’s favorite Photoshop CS5 features. What features excite you the most? Which ones are you most interested in learning about? We’re interested in your comments, which you can leave below.
